Cosmic Ultimate UST Carbon Wheel

What Our Gearhead® Experts Are Saying:

"These are the definition of a no-compromise race wheel. The carbon spokes and monobloc construction make them insanely stiff yet still smooth. Every watt goes straight to the road, and the aero shape feels steady even when the wind picks up. They’re the kind of wheels you feel every time you accelerate—it’s pure performance."

For elite riders who demand world-class speed, precision, and efficiency, the Mavic Cosmic Ultimate 45 Disc 19mm front and rear wheels set the standard. Handmade in France from unidirectional carbon, each wheel is crafted as a single structural unit—rim, spokes, and hub working in perfect harmony. The 45mm NACA aero rim profile reduces drag while maintaining rock-solid stability, delivering the fastest, most responsive wheelset in Mavic’s storied lineup.

The R2R carbon spoke system runs continuously from rim to rim, eliminating junction points and ensuring consistent stiffness under heavy torque. This unique monobloc architecture makes the wheels both lighter and stronger than conventional laced designs, while the high carbon hub flanges improve tension balance and lateral rigidity. Paired with Mavic’s tapeless UST tubeless technology, setup is effortless and performance is immediate—lower rolling resistance, better compliance, and fewer flats.

At the core, the Instant Drive 360 freehub provides lightning-fast 9° engagement, while QRM sealed cartridge bearings maintain perfect preload for a frictionless spin. The front hub’s 12x100mm spacing and rear’s 12x142mm setup pair perfectly with Center Lock brakes for confidence in all conditions. At just 1255g per set, the Cosmic Ultimate 45 Disc front and rear wheels redefine what’s possible in aerodynamic, lightweight design—purpose-built for the fastest riders on the planet.
